Campaign: Parker Solar Probe 11th Perihelion

February 18 - 28, 2022

PSP's 11th encounter was on February 25th, 2022. This perihelion was Earth-facing and was well-observed from Earth, and also Solar Orbiter was close by. We expected one low-latitude coronal hole on the Sun from which high-speed streams should be seen by PSP, as well as several active regions on the solar disk. During this encounter, we focussed the observations on the coronal hole and the associated high-speed stream, on switchbacks and their solar counterparts in the lower atmosphere, and on flares and the associated energetic particles in the inner heliosphere. Remote observations of PSP's crossing of the solar disk focussed on February 24th to 26th, and off-limb observations at larger distances of PSP to the Sun at the period before and after.
